Breakfast for me is normally a hot one to start the day off well (instant oats or the like, MartinK9 was having shepherd's pie for his).
Lunch is dependant on the day sometimes hot sometimes cold, but normally with a warm drink either squash, chocolate or coffee or tea for me.
snacks for me are generally stuff like chocolate, trail mix, dried fruit, fruit leathers, oat cakes and sweets.
Evening meal will be the group one, mainly either pasta, cous cous, or the like as the base with added extras like soups and dried sauces, with some meat (hotdogs (locally purchased and we were in Norway) etc). No mushrooms as Chris does like them but will have extras too. We can supplement this with locally bought food and anything we get. But generally that is a good base to start from.
On food you take out with you try to get it as light as possible dehydrated and powdered is the best, heavier stuff meats/fresh/etc be bought out there.
If you are looking at the calories aim for around 3000-4000+ a day as a rough guide.
For the group meals we need to know of any dislikes so we can plan for them.
TinkyPete: No mash potatoes
Chris: No mushrooms
The rest of you please add to this so we can start to plan for the food
